[summary of the invention]
For solving the problems referred to above that exist on the prior art, the utility model aims to provide a kind of belt transmission device for screw rod type compressor, and this device only needs to adjust the purpose that master and slave belt pulley gap just can realize adjusting belt pulley planeness and parallelism easily; Not only Component are few, the manufacturing cost is low and the assembling is simple, and the precision between the master and slave belt pulley is easy to adjust to the expection requirement, help reducing complete machine oscillation, reduce noise, increase the service life, thereby guarantee the complete machine Performance And Reliability.
For solving the problems of the technologies described above, the utility model has adopted following technological scheme: this belt transmission device for screw rod type compressor, comprise the mounting plate of settling motor and screw rod machine, driving wheel and follower are fixedly installed on respectively on motor reel and the screw rod arbor, drivign belt is looped around driving wheel and follower periphery, it is characterized in that: described mounting plate is two separate motor mounting plates and screw rod machine mounting plate, motor mounting plate is vertically to the dead ahead that is fixed on motor, on the motor mounting plate outerplanar, the bolt hole that is used to admit described bolt is for vertically to the long waist shaped hole through bolton for screw rod machine mounting plate; On the motor mounting plate below the screw rod machine mounting plate lower end surface, be provided with the controlling device that is used for adjusting screw rod machine mounting plate setting height(from bottom).
As to technique scheme further replenish and perfect, the utility model also has following additional technical feature.
Described long waist shaped hole is four of two row, is located on the motor mounting plate.
Described controlling device has two covers, be the symmetry shape setting, every cover controlling device is made of adjusting bolt block, adjusting bolt, regulate bolt block and motor mounting plate and form an integral body, the adjusting bolt revolves to put from bottom to top to be regulated on the bolt block, regulates the upper-end surface of bolt and the lower end surface of screw rod machine mounting plate and offsets.
Beneficial effect: compared with prior art, the utility model adopts motor and the flat drive mechanism that is connected up and down of screw host, motor is placed on the below, its weight and casing rigidity have strengthened the soil rigidity of transmission device, screw host up, because the transmission pulling force of belt is offset favourable operating steadily with the deadweight that is fixed on the screw host on the mounting plate.Adopt plank frame, not only component are few, the simple cost of manufacturing is low, and install easy to adjust, during adjustment if adjust simply belt pulley axial position, regulate principal and subordinate's belt pulley spacing by controlling device and can realize that belt adjusts purpose, and axis parallel degree need not to adjust and can be guaranteed by the mounting plate planar processing precision, be easy to guarantee the assembly precision of component, realize the steady transmission of belt.
The utility model is described further by embodiment below in conjunction with accompanying drawing.
[description of drawings]
Fig. 1 is an embodiment's of the utility model a main TV structure schematic representation, and foreshortened figure has been made in long waist shaped hole 61 among the figure.
Fig. 2 is the right TV structure schematic representation of Fig. 1.
Fig. 3 is the main TV structure schematic representation after body mounting plate and motor mounting plate decompose among Fig. 1.
Among the figure: follower 1, screw rod machine mounting plate 2, lower end surface 21, fixed hole 22, attachment hole 23, screw rod machine 3, screw rod arbor 31, bolt 4, nut 41, connecting through hole 42, drivign belt 5, motor mounting plate 6, bolt 62 is regulated in long waist shaped hole 61, regulates bolt block 63, driving wheel 7, motor 8, motor reel 81.
[embodiment]
Referring to Fig. 1, and in conjunction with Fig. 2, Fig. 3.Screw rod machine mounting plate 2 and motor mounting plate 6 are two separate surface plates, and the both has several through holes.Be positioned on the motor mounting plate 6 of below, the middle part has the through hole of admitting motor reel 81, the periphery has connecting through hole 42, the top has four vertically to the long waist shaped hole 61 of admitting bolt 4 with screw rod machine mounting plate 2 laps, and the purpose that long waist shaped hole 61 is set makes the screw rod machine mounting plate 2 can be vertically to lifting.Be positioned at the top and be stacked on the screw rod machine mounting plate 2 on motor mounting plate 6 outerplanars, the middle part has the through hole of admitting screw rod arbor 31, and the periphery is provided with attachment hole 23, has four fixed holes 22 with 61 corresponding sections, long waist shaped hole.
